C # XAML - Getting XAML content property (contentControl.Content)
So I have an AML keyboard as such:
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<TextBox Name="btnTotal" Width="280" Height="60" Grid.ColumnSpan="3" Grid.Row="0" Margin="10,10,10,10" Background="#302F37" Foreground="AntiqueWhite" FontSize="35"></TextBox>
<Button x:Name="btnZzero" Content="0" Width="80" Height="60" Grid.Column="0" Grid.Row="4" Margin="5,5,5,5" Background="#302F37" Foreground="White" Focusable="False" Click="btnZzero_Click"></Button>
<Button x:Name="btnOk" Content="OK" Width="80" Height="60" Grid.Column="1" Grid.Row="4" Margin="5,5,5,5" Click="btnOk_Click" Background="#FF8FC377" Focusable="False"></Button>
<Button x:Name="btnCancel" Content="Cancel" Width="80" Height="60" Grid.Column="2" Grid.Row="4" Margin="5,5,5,5" Click="cancel_Click" BorderBrush="Black" Background="#FFD64D4D" Focusable="False"></Button>
<Button x:Name="btnOne" Content="1" Width="80" Height="60" Grid.Column="0" Grid.Row="3" Margin="14,6,0,6" Focusable="False" Background="#302F37" Foreground="White" HorizontalAlignment="Left" Click="btnOne_Click"></Button>
<Button x:Name="btnTwo" Content="2" Width="80" Height="60" Grid.Column="1" Grid.Row="3" Margin="5,5,5,5" Focusable="False" Background="#302F37" Foreground="White" Click="btnTwo_Click"/>
<Button x:Name="btnThree" Content="3" Width="80" Height="60" Grid.Column="2" Grid.Row="3" Margin="5,5,5,5" Focusable="False" Background="#302F37" Foreground="White" Click="btnThree_Click"/>
<Button x:Name="btnFour" Content="4" Width="80" Height="60" Grid.Column="0" Grid.Row="2" Margin="5,5,5,5" Focusable="False" Background="#302F37" Foreground="White" Click="btnFour_Click"></Button>
<Button x:Name="btnFive" Content="5" Width="80" Height="60" Grid.Column="1" Grid.Row="2" Margin="5,5,5,5" Focusable="False" Background="#302F37" Foreground="White" Click="btnFive_Click"></Button>
<Button x:Name="btnSix" Content="6" Width="80" Height="60" Grid.Column="2" Grid.Row="2" Margin="5,5,5,5" Focusable="False" Background="#302F37" Foreground="White" Click="btnSix_Click"></Button>
<Button x:Name="btnSeven" Content="7" Width="80" Height="60" Grid.Column="0" Grid.Row="1" Margin="12,5,9,6" Focusable="False" Background="#302F37" Foreground="White" Click="btnSeven_Click"></Button>
<Button x:Name="btnEight" Content="8" Width="80" Height="60" Grid.Column="1" Grid.Row="1" Margin="5,5,5,5" Focusable="False" Background="#302F37" Foreground="White" Click="btnEight_Click"></Button>
<Button x:Name="btnNine" Content="9" Width="80" Height="60" Grid.Column="2" Grid.Row="1" Margin="5,5,5,5" Focusable="False" Background="#302F37" Foreground="White" Click="btnNine_Click"></Button>
Now I want to write a small helper method to trigger on each button click, but I can't figure out how to use the content from XAML.
for example this works for button 1:
private void btnOne_Click(object sender, RoutedEventArgs e)
{
addButtonNumberToResult();
}
And the helper method uses btnOne.Content, but how do I get it to use the content from any button clicked? So I can just add a helper method to each button?
private void addButtonNumberToResult() //helper method
{
if (btnClicked == true)
{
btnTotal.Text = "";
btnClicked = false;
}
QuantityResult = QuantityResult += btnOne.Content;
btnTotal.Text = QuantityResult;
}

You can use a variable sender
to define the pressed button:
private void btn_Click(object sender, RoutedEventArgs e)
{
addButtonNumberToResult((Button)sender);
}
add btn_Click
to Click
each button event (and replace the ones you already have)
private void addButtonNumberToResult(Button btn) //helper method
{
if (btnClicked == true)
{
btnTotal.Text = "";
btnClicked = false;
}
QuantityResult = QuantityResult += btn.Content;
btnTotal.Text = QuantityResult;
}
